问题 When an organism is completely encapsulated and preserved, it becomes a fossil, therefore turning into evidence of things that once lived.

选项 A、thereby
B、as a result of
C、so
D、in the end

答案A

解析 therefore和thereby均为副词,表“因此”,但therefore后通常跟一个句子;而thereby后常接现在分词作状语。as a result of“由于”(as a result才表“因此”),因此A为答案。
